There are six kinds of reasons of common malfunction in the running process of submersible deep well pump.
(1) can't flush or a serious shortage of head: when the water pump when turning the phenomenon, and deep well pump, when idle, and large noise, this phenomenon is mostly in the form of deep well pump bearing damage.
(2) sealed: water pump motor shaft extension end has a double mechanical seal parts, it USES high wear-resistant materials, deep well pump in use after a period of time, seal caused by wear or natural aging sealed water seepage and leakage. In addition, in the mechanical fitting surface have a circular rubber sealing ring form a seal to prevent water seeping into the pump body, but as a result of deep well pump use motor speed is very high, in the long-term use of mechanical seal face inevitably caused serious wear and tear.
(3) the damaged pipe leakage: crane can be heard in the deep well pump in the deep well pump wheel normal voice also normal rotation (meters), but no water or only a small amount of water, this kind of situation is mostly water pipe has been damaged.
(4) card pump: the pump does not turn, but could hear the buzzing sound, the pump impeller by foreign bodies stuck mostly. For example, our school well water water quality concentration due to geological reasons cause damage of filter cover.
(5) leakage, leakage is one of the most common fault pumps, performance for the knife on the failure phenomenon, leakage protector in the transformer room automatically trip, this is due to the deep well pump motor winding leakage phenomenon caused by the water in the body.
(6) start capacitor failure: buzzing sound can be heard when the power is connected, but not a deep well pump motor;If then gently touch the impeller, multistage deep well pumps can immediately turn can determine for capacitance has been damaged.
